METALLIC COLUMN.

SPECIFICATION forming part of Letters Patent No. 611,019, dated September 20, 1898. Application filed November 8, 1897. Serial No. 657,850. (No model.)

T0 aZZ whom it may concern:

Be it known that I, ALEXANDER NURICK, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Metallic Columns, of which improvement the following is a specification.

My invention relates to columns, posts, or struts of the general class or type in which plates or shapes of rolled metal of suitable length are disposed about a common axis and connected by a longitudinal line or lines of rivets; and its object is to provide a column of this class which shall embody the advantages of great strength and stifiness without undue or excessive weight, economy of manufacture within a large range of sizes and areas, and facility of connection to other members of the structure in which it is employed.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a transverse section through a column embodying my invention; Fig. 2, a side view in elevation of a portion of the same; Fig. 3, a similar view of a portion of a column, showing other attachments; Fig. 4, a transverse section through a column of smaller trans verse section with plates intermediate of its members, and Fig. 5 a side view in elevation of a portion of the same.

In the practice of my invention I construct a column, post, or strut of four rolled-metal shapes of any suitable and desired length and of the form in section commercially known as a channelthat is to say, composed of a flat web 1 and flanges 2, extending at right angles to the web, at the ends and on the same side thereof. The channels are placed in a bending-machine, the construction and operation of which are familiar to those skilled in the art and which does not constitute any part of my present invention, and the webs 1 are bent upon their longitudinal middle lines and to a comparatively short radius until the portions on each side of the curved middle portion thus formed stand at right angles one to the other, with the end flanges 2 projecting in the direction of the convex surface of the middle portion. The bent channels are then brought together, so that each end flange of jacent channel and are united by seams of rivets 3, passing through each of the four pairs of abutting flanges. When found desirable or necessary, plates or sheets 4 may be interposed between the adjacent faces of the flanges on either two or four opposite sides of the column, as shown in Figs. 4 and 5, and connected thereto by the seam of rivets which ronnects the flanges, said interposed plates serving to strengthen and stiffen the column as well as to afford points of attachment for braces, ties, or other members of the structure in which the column is to be used.

By reason of the employment of channels which are a standard commercial shape produced in quantity by first-class rolling-mills myimproved columns may be constructed at much lower cost than those which involve the use of sections which require to be specially rolled, and it will be seen that the disposition of the metal is in the most favorable position for strength and stability-that is to say, at the outside of'the column. A special feature of advantage is also provided in the facility which is afforded for making any connections to the columns, which may be required for structural purposes, by reason of the large area of flat surface which is presented on each side of the column, the necessity for special fittings to receive connections, which is found in many other forms, being obviated.

The drawings illustrate anumber of forms of connections which are available. Thus the column shown in Figs. 1 and 2 may be connected' to that of Fig. 3 by an I-beam 5, which is shown as riveted to angles 6, having one side cut away, so that they may fit over the projecting flanges 2 of the columns, and riveted to the flat sides thereof on opposite sides of the flanges. Two I-beams 5 5 are shown in Fig. 2 as connected to the column by plain angles 7 and T-irons 8 on each side of a pair of flanges, and in Fig. 3 a portion of a pair of flanges 2 is cut away to admit the end of an I-beam 9, which is connected to the column by angles 10, riveted to its web, and angles 11, riveted to the flanges on one of its sides.

Two columns may be connected in line longitudinally by an interposed plate 12, angles 13, and rivets 14. Figs. 4- and 5 show a column of smaller section, but bent on the same radius of curvature, so as to be formed by the same dies, and having plates 4 interposed between the members of opposite pairs of its flanges. Connections may be made to the plates 4, if desired. The column of Figs. t and 5 is shown as connected to a foundation 16 by a plate 17, holding-down bolts 18, and angles 19, riveted to the flat surfaces of the column and to the foundation-plate 17.

I claim as my invention and desire to secure by Letters Patent 1. A metallic column composed of four rolled flanged metal bars, bentat right angles about their longitudinal middle lines with flanges outwardly projecting, and with the central portions of their webs curved and the remainder flat surfaces, and connected by seams of rivets passing through their flanges, substantially as set forth.

2. A metallic column composed of four rolled-metal channels, bent at right angles about their longitudinal middle lines with their flanges outwardly projecting and with the central portions of their Webs curved and the remainder flat surfaces, and connected by seams of rivets passing through their flanges, substantially as set forth.

3. The combination in a metallic column, of four rolled flanged metal bars bent at right angles about their longitudinal middle lines with their flanges outwardly projecting, and with the central portions of their webs curved and the remainder flat surfaces, and connected-by seams of rivets passing through their flanges, and an angle-plate riveted to a flat side of the column for the attachment of a lateral connection thereto, substantially as described.
